In the 1970s, Gene experimented with musical compositions using a device with four square-wave voices, whose tuning was very stable and accurate, being controlled by a [[http://en.wikipedia.org/wiki/Crystal_oscillator|crystal oscillator]]. The device in turn was controlled by HP [[http://en.wikipedia.org/wiki/HP_9800_series_desktop_computers|HP 9800 series desktop computers]], initially the HP 9830A, programmed in HP Basic, later the 9845A. Using this, he explored both just intonation with a particular emphasis on groups of transformations, and [[pajara]].
